Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a watch suitable for use by security guards.

[Technical background of the invention and its problems]

The purpose of such a device is to enable security personnel, who are supposed to be making patrols under fairly limited conditions, to effectively navigate through specific routes for their patrols and to be able to actually visit various locations at specified times. The purpose is to confirm that you visited the place.

In order to monitor such patrols, the device includes a recording device carried by the security guard along with a plurality of identification keys permanently fixed at the various locations where the verification has to be carried out. As the security guard passes through each of these locations, he inserts a key carrying location identification means into the recording device. When the device is actuated by said key, the identity of the location and the time of passage are recorded on a recording medium, the latter being provided by a clock mechanism (hereinafter referred to as "moviment") within the portable device. The data storage medium can be removed from the portable device periodically to ensure that the security guard has carried out his patrol under the defined conditions.

There are two main types of security guard watches, depending on the passage through a special location and the way in which information about said passage time is recorded. In a first type of device, a data medium, which may be a disk or tape, is driven continuously by a clock motion and data representing each location is printed on the medium. The position of said record relative to pre-printed time marks on the medium indicates the time at which the corresponding passage occurred. This type of recording has the disadvantage that it requires a large recording medium. Furthermore, the storage medium is used up as a function of elapsed time rather than as a function of the number of location checks performed. Additionally, time analysis is poor.

In other types of devices, the data medium is generally in the form of a tape and is moved one step each time the identification key is used. Under the influence of the action of the key, the mechanism prints the time given by the clock movement together with the identity of the key's location.

This second type of device has the advantage that it uses up less recording medium, thus lasts longer between refills, and provides improved analysis. However, in this type of device, the drive chain that connects the clock (which may be mechanical or electronic) to the data printing means and also to the external time-display means is relatively complex and fragile. Furthermore, the printing means of such a device consists of a reel with surrounding Arabic numerals on which hours and minutes or even minutes can be printed. Manufacturing such printing wheels is expensive because complex molds are required to allow the parts to be removed from the mold.

[Purpose of the invention]

The present invention is of the second type, i.e. the data carrier is moved only when recording is being made on the delta media, but the driving chino for printing said data is simplified and the printing element tube is The object is to provide a security watch which compensates for the above-mentioned disadvantages by providing a patrol monitoring device of a type that can be manufactured at reduced costs.

[Summary of the invention]

The present invention provides a device for monitoring the passage time of a security guard through a number of given locations, the device comprising a plurality of keys, each key intended to be placed in each of said locations. and each key is provided with a printing element capable of identifying said location, the device further comprising a recording strip for simultaneously recording data indicative of one of said locations together with the time of passage of said location. The portable recording device has at least a clock movement having a time axis, and a disk fixed to rotate around the axis, and the disk has a time axis. said portable recording device having a printing element disposed around one side thereof for printing data, and said portable recording device allowing one of said keys to be inserted into said recording device and said portable recording device having a printing element arranged around one side thereof for printing data; means for positioning said identification element thereon; and means for advancing the glaze recording strip one step, said strip advancement means causing a new portion of said strip to move onto said disc at each step. Arranged opposite the printing element above and opposite the identification element of the key, the recording device further comprises means for causing simultaneous printing of time data and an identification element on the part of the strip.

In this way, the printing mechanism and the clock movie are limited to the ordinary clock movie, and the printing element for printing time information is directly fixed or made of a disk fixed to the time axis of the clock movie. It can be seen that the printing mechanism and clock movement are very simple. Furthermore, since the printing element is fixed around one side of the disc, the disc can be shaped without particular problems.

[Implementation sequence of the invention]

Embodiments of the present invention will be described in detail below with reference to the drawings.

First, with reference to FIGS. 1 and 2, the overall configuration of a portable recording device that constitutes a part of a security guard's watch will be described. The device has a substantially cylindrical nose 12, and this I.
The housing is penetrated by a window 16, which is made of glass 1
There is a front face 16 closed by 8.

Inside the housing 12 is a standard watch 20 having a time axis n and a minute axis. This clock movement can be of mechanical or electrical type. Such motions are well known, so it is pointless to describe them in detail.

The hour hand and minute track are respectively rubbed onto the shaft 2 and the end of the shaft. These hands cooperate with fixed time marks 30 provided on the inner surface of the glass 18 or on the housing.

The watch movement also has a seconds axis with a pointer 32 attached to the end to indicate when the mechanism is in operation. Thus, the user of the device can verify that the device is working and that it shows the correct time. Thus, the drive chain for displaying the time is very simple as it is just a standard clock movement.

The disk A is attached to the time axis O and is therefore rotated by the time axis O. A printing element with the general reference numeral 36 is attached to the rear side around the periphery of said disc. These elements are arranged so that they can be printed in the manner described below, along with minutes of time. As can be seen more clearly in FIG. 4, these printed elements may include intermediate marks indicating a shorter time by interpolation from, for example, a gifted portion, a fixed mark.

The fil 11 side of the housing 12 has an orifice 40 suitable for receiving an identification key such as 42. 42 keys, 44 bits fixed to the key body
and a movable bit 4 that rotates half freely at the end of the key 42.
6. The second or movable pit 46 has printed letters on its surface line which characterize the location where the key has to be found, these printed letters can for example consist of numbers.

As seen in FIG. 1, the printing element 48 of the key is placed in the same plane as the printing element 36 directly above the disc. The first or fixed pin (44u) of the key, which can be rotated by turning the key, serves to drive the strip between the recording sheets, as will be explained later, and is used to
It also helps to make 2 work. As seen in FIG.
Move the movable bit 46 of the cutter 42 so that it is above 6.
It moves so that it is above the upper printing element 48. of course,
The strip has these printing elements 36 and 48 and a printing mark 5 arranged opposite said printing elements.
Move between 2 and 2.

FIG. 4 shows a portion of the printing strip indicia, on which the identification elements of the key 42 are recorded (in this case) in the form of the number 153, together with the printing elements of the disc facing the print head. In the example in Figure 4, these are 091O and 0920.
is shown as time data to be displayed.

As can be seen more clearly in FIG. 2, the strip of the recording paper blade passes between the hammer and the printed element 48 on the key and the area between the printed elements on the disc corresponding to the display time. move to. The strip strip is made of a no-carbon (NOR) paper, ie, a paper in which the image of the printing element is effectively revealed simply by the hammering of the strip against the printing element.

When the key 42 is fully engaged, the movable bit 46 is prevented from rotating by a slot 54 in the housing and one fixed pit 44 is received in a rotating block 56 having a slot 58. The fixing bit 44 engages with.

Thus, when the key 42 is rotated, the movable bit 46 remains opposite the print head while the fixed pin 44 causes the block 56 to rotate.

As shown in FIG. 3, the block 56 is fixed to a cam 60, the outer circumference of which cooperates with the lower part 62 of a lever 64, which is mounted for rotation about an axis 66ff. The edge 62 of the lever 64 is pressed against the cam 6 by the spring 68.
It is kept in contact with the outer circumference of 0.

In FIG. 3, block 56 is in a neutral position in which a key can be inserted. Block 56 is held in this position in part by cooperation between a ratchet 72 and a notch 74 on the outer periphery of cam 60. In addition, ratchet 72 forces rotation from this position in the direction marked by arrow f. The bottom edge 62 of the lever 64 is the cutout 7
8 and a projection 73 which, in the neutral position of the block, cooperates with a second notch 76 on the outer circumference of the cam. In the neutral position, printing hammer 72 is held slightly above the strip of paper 50. Beyond the notch 76, the cam 60
The outer periphery of the slope defines a ramp 80, and this ramp
It ends with 2. Beyond the drop 82 , the cam has a second ramp 84 , which terminates in a notch 74 .

When block 56 is rotated from its neutral position in the direction indicated by arrow f, ramp 80 lifts lever 76;
Eventually, the drop portion 82 comes into contact with the protrusion 73.

Beyond this angular position of the block, the drop 82 of the cam and the cutout 78 of the lever 64 cooperate to cause the lever to move abruptly downward so that the printing hammer strikes the printing element. One end of the print media paper strip circle is connected to the drive reel 86
Fixed. This reel 86 itself is rotatably fixed to a star wheel 88. The rotational movement of the lever 640 under the cam 600 is also useful for moving the Kishikoichi 88 forward by 2 steps.

To do this, a ratchet 90 is pivotally mounted to the free end 92 of lever 64. A return spring 94 forces the end 96 of the ratchet 90 against the teeth of the star wheel 88. In addition,
A second ratchet 98 prevents star wheel 88 from reversing opposite the direction indicated by arrow f' (third
(see figure).

In this manner, when the lever 64 moves downward with the drop portion 82 received in the cutout portion 78, the ratchet lever 9th end 96 passes under the next tooth of the star bar 88.

When the main lever 64 is lifted, the end 96 of the ratchet lever 90 contacts the law tooth and rotates it through an angle that matches one tooth. This rotation causes
The strip between the sheets advances one step. The device is then ready for the next recording. When the block is returned to the neutral position shown in Figure 3, the key can be removed.

As seen in FIGS. 1 and 2, the mount also has a mechanical system for absorbing the angular offset of the printing disk caused by clock motion. This mechanical system consists of a resilient blade 1 with a fixed end 102;
00. When the blade 100 is stationary,
The other end 104 is free. When the key 42 is inserted,
The end of the key pushes against a rod 106 that is slidably mounted in an orifice 108. The end 110 of the rod 106 deforms the elastic blade 100 so that its end 104 rubs against the rim of the disc, thereby absorbing the angular deviation of the printing disc caused by operating slack due to clock motion. (See Figure 2). This kind of rubbing action is
Continue with 1 when the key is retracted.

Furthermore, the device has additional printing means for distinguishing between AM and PM. This additional printing means 112 is pivoted about a fixed axis on a fixed plate 114. Said additional printing means may include the letters A and P, for example. A member 112 is fixed for rotation with a toothed wheel 116.

The toothed wheel 116 can cooperate with a member 118 fixed to the disc. Each time the disk tone rotates one complete revolution, ie at the end of each 12 hour period, the unit 112 rotates one quarter of a revolution. Therefore,
The letters A and P appear alternately opposite the print head for printing onto the paper.

FIG. 5 shows a modified embodiment of the portable device, in particular of the time display means. In this implementation, the disk 130 fixed to the time axis 132 still carries a printing element 134 for printing time information on the outer periphery of its rear side.

However, on its front side, ie on the side visible through the glass, the disc 130 has a mark 136 for indicating the time, which replaces the hour hand. However, both the minute hand and the second hand are retained to indicate that the clock movement is working.

FIG. 6 shows another implementation of the means for printing the time. The first disk 150 is the time axis 1 of the clock movement.
52 for rotation.

The periphery of the side of the disc 150 facing towards the movement has printed elements for the number of hours, for example element 154.

The second disk 156 is the clock moupimen) 200 minute axis 158
It is fixed so that it can rotate. A disk 150 is located between the watch movie 20 and the disk 156. In addition, the disc 16 is transparent and has a thick rim 160 with a printing element 162. The thickness of rim 160 is such that printing elements 154 and 162 are arranged in a common plane perpendicular to axes 152 and 158. Figure 6 also shows
The identification element fixed to the movable pit 46 of the key is shown in a simplified manner along with the print hammer 52 and the print media.

Furthermore, the opaque plate 150 has a mark 170 serving as the hour hand, and the three-sided disc 156 has a mark 172 serving as the minute axis. This solution makes the device somewhat more complex since it requires an additional display disk, but it also makes it easier to stitch the strips. Because disk 16
0 may have 60 print elements corresponding to 60 minutes.

To accommodate a wide range of shapes and tolerances for printing elements 112, printing hammer 42 can be divided into two parts.

FIG. 7 shows that the time printing elements 112 and 36 are
2 and the printing element 640 is shown being struck by the hammer 200 leaning against the lever 640 surface 204. In the rest position, the hammer 2 belonging to the rising part 202
The reference plane of 00 is the pin 206 that belongs to the rising portion 202.
and 208 at an angle to and spaced apart from the surface 204 of the lever 64. These bottles are fixed to the lever 64 and directed toward the hole 210 of the bottom part 212, while the flask 640' slides in the slot 214 and the compression spring 216 is supported on the lever 64 and the riser 202. has been done.

Suitably selecting the characteristics of the hammer 200, its resting position relative to the surface 204, and the stiffness of the spring 16.
This allows the impact energy to be distributed over the time elements 112 and 36 of the clock movement and over the element 48 of the key 42 so as to obtain a print quality that is independent of variations in dimensions and tolerances of the printing elements.

From the above description, it is clear that the construction of the snow and equipment clock according to the invention is greatly simplified with respect to the construction of similar prior art devices. Special exception.

The means for printing time data has been reduced to a disk attached directly to the time axis of the clock movement.

Furthermore, it is easier to mold the disk because the printing element is not placed on the rim of the disk, but on one of the main surfaces of the disk.
